FILTER, CLEANER, on WASHER, FOR are...

To aZZ whom it may concern lle it known that 1, Jon RUoLorr, a citizen of the United States, residing at Gallup, in the county of McKinley and State of New Mexico, have invented certain new and useful Improvements in Filters, Cleaners, or Washers for Air, of which the following is a spm-ification, reference being had to the accompanying drawings.

This invention relates to an air filter, cleaner or washer, particularly adapted for use in connection with automobiles, tractors and motor driven trucks and the like and gas and oil burning engines, for filtering, cleaning, or washing the air prior to entering the carburetor.

()ne of the objects is toprovide an apparatm of this kind including a container for the water and wherein the air is allowed to enter the container'at the top and conveyed to a point adjacent the bottom thereof so that it can percolate upwardly through the water for cleansing or washing purposes and then screened and allowed to pass off into the carbureter.

Another object is to provide a device of this character wherein provision of means is afforded for holding the screening or filtering means in place at a point above the level of the water and furthermore to provide means for indicating the level of the water in the container and also the provision of means for draining the sediment or refuse from the bottom of the container.

Vhile the design and construction at present illustrated and set forth is deemed preferable, it is obvious that as a. result of a reduction of the invention to a more practical form for commercial purposes, the invention may be susceptible to changes, and the right to these changes is claimed, provided they are comprehended within the scope of what is claimed.

The invention comprises further features and combination of parts, as will be hereinafter set forth, shown in the drawings and claimed.

in the drawings Figure 1 s a vertical sectional view through the improved filter, cleaner or washer constructed in accordance with the invention, 1

Fig. 2 is a cross sectional View through, the same on line 2-2 of Fig. 1.

Referring to the drawings 1 designates a container which may be of any suitable Specification of Letters Patent.

size, shape or configuration and may be constructed of any suitable material preferably metal. The upper end of the container has threaded thereon a closure or cover 2. An outlet pipe 3 is threaded to a flanged opening 4 so as to carry off the air subsequently to it having been cleansed. This pipe 3 is designed to connect in any suitable manner with the air intake of a carburetor in order to insure a superior mixture for gas and oil burning engines.

The interior surface of the wall of the container has an annular shoulder 5 on which is supported the ring of a spider or web 6. A second web or spider 7 is ar ranged in the container and is spaced a little above the first web or spider. Interposed between the two webs orspiders is a plurality of wire fabric disks 8 and intermediate fiber members 9 which are constructed of wool or the like.

By means of the spiders or webs the disks and the intermediate fiber members are held tightly together and even. The upper spider or web has a bearing 10 as shown. Adjustably threaded at 11 in a bushing 12 of the closure or cover 2 is a screw 13 to the lower end of which a collar 14 is swiveled in any suitable manner. The upper end of the screw carries a hand wheel 15 whereby the screw may be adjusted. Suitably secured to the collar as at 16 are the arms of an elliptical bowedspring 17, the elongated curved part 18 of which engages a transverse groove 19 of the bearing 10. By means of this bowed spring the upper spider or web is forced relatively tight against the wire fiber disks or screens and the fiber members so as to hold them securely in place and'even. It will be n ted that by adjusting the screws in one direction or the other, the pressure on the spiders or Webs can be increased or decreased as may be desired in order to hold thefiltering and screening members in position. It has been found that in case the air which is filtered, cleansed or washed by means of this apparatus is being utilized relatively rapid, the screw may be adjusted in order to tighten up the screening and filtering members, thereby preventing the air from passing therethrough too rapidly. Furthermore. if it is found necessary to allow the air to pass off in a relativelv greater volume, then the screw may be adjusted in the opposite direction, to permit the filtering and screening members to separate, in other words, 'to' be supported and held relatively loose in Which case the air will pass therethrough' I terminating a short distance from the bottom of the container. T he upper end of this pipe or tube is outwardly flared as shown at 21 so as to permit the air to more freely enter the pipe or tube. The air passes downwardly through the tube and is allowed to escape into the container at a point very close to the bottom of the container so that the airwill-have to percolate through the body of the water. The air, after passing through the body of the water, is screened or filtered through the screening or filtering members and is then allowed to pass off through the pipe or tube 3 into the carbureter where it may be used for facilitating the mixture in the carbureter. In other words, it is the aim of the invention to provide a device which has been found to thoroughly cleanse or wash the air in order to furnish pure air into the carbureter. The container on the exterior thereof has connected thereto a conventional form of water gage 22 provided for the purpose of disclosing the level of the water in the container. connected to the container as at 23 and may be graduated as may be found necessary or convenient and furthermore, the gage may be of any type or diameter as may be found suitable for the purpose intended. Connected to the container near the bottom is a drain cock 24, especially provided for the purpose of draining off the sediment or refuse which in time collects in the bottom of the container.

This water gage 1s The invention having been set forth, what is claimed as new and useful is 1. In a filtering device for an air cleaner and washer, a casing having on its interior surface an annular supporting rib, upper and lower spaced spiders, the lower one being supported upon the rib, wire fabric spaced disks engaging the adjacent faces of the spiders, a wool filtering disk interposed between the wire fabric disks, a bowed elongated spring having one of its elongated bowed parts bearing centrally upon the cen tral portion of the upper spider, and a screw threaded in the top of the casing and having its lower end operatively and swivelly connected to the other elongated bowed part of the spring, whereby upon adjusting the screw through the top of the casing the tension of the bowed spring may be regulated for increasing or decreasing the constant pressure on the upper spider, so as to govern the density of the filtering means between the spiders.

2. In a filtering device for air cleaners and washers, a casing, a filtering means in the casing, said casing having means to support the filtering means, an adjustable screw threaded in the top of the casing axially concentric with the filtering means, a plate hearing upon the filtering means, and a bowed elliptical spring swiveled and operatively connected to the lower end of the screw and having one of its elongated bowed portions bearing centrally upon the central portion of the plate, whereby upon adjusting the screw, the tension of the spring may be regulated to increase or decrease the constant pressure on the plate, hence governing the density of the filtering means.

In testimony whereof I hereunto affix my signature.
